Archived bulletin
The site's reference BIPOL bulletin (Q4 2025) contains no PDF for this municipality. The figures come from the bulletin of Q2 2025 (closed 31/10/2025), preserved by the Internet Archive Wayback Machine. Only complete years are included (2000, 2015-2024) : the last column of this bulletin covers only part of the year. Older closing date, so figures are not revised and may be slightly lower than in a recent bulletin. Archived PDF.

Definitions
- « Foreign national » = person with a non-Belgian nationality in the national register, on 1 January. Naturalised Belgians or Belgians of foreign origin are counted as Belgians.
- Origin (Statbel): based on current nationality, the person's first registered nationality and that of their parents. Official categories: Belgian of Belgian origin, Belgian of foreign origin, non-Belgian.
- Group of nationality of origin: Statbel grouping into neighbouring countries, EU27 excluding neighbouring countries, and non-EU27; this is not a strict EU / non-EU split (the United Kingdom is classed as a neighbouring country).
- Merged or renumbered municipalities: no reconstructed series before the date of the new code (same rule as for the reference population).
- These figures are not cross-referenced with any crime statistics.
